Koenig & Bauer’s CorruCUT is a new sheetfed flexo press and die cutter designed for direct printing on corrugated board. The OEM added that it’s designed with extremely robust mechanical engineering paired with maximum ease of operation and maintenance. “Its strong durable side frames are made from cast iron poured to shape at 1300 °C at the foundry, which displays almost no vibrations. It combines proven technology with modern electronics and intelligent automation for a high-performance production tool geared to all current demands of the corrugated industry.”
“Corrugated customers are seeking machines with faster set-up and more automation as well as tailor-made solutions for their specific environment,” said Jeff Dietz, Vice President of the Web & Specialty Press Division at Koenig & Bauer (U.S.). “Waste handling in the corrugated process is a big concern as is colour consistency and repeatability for brands. We believe that the new CorruCUT will satisfy the needs of printers who require high graphic corrugated printing and converting machines that are faster and more cost-efficient to operate. Our CorruCUT Flexo Press will enable us to further consolidate our strong position in the growing packaging market.”
The CorruCUT incorporates a number of unique features such as a vacuum-belt feeder without infeed roller, a new solution for anilox roller exchange, and overhead vacuum delivery. It handles corrugated sheets with a width of up to 110 inches and a thickness of 0.354 inches, running at speeds up to 12,000 sheets per hour. Koenig & Bauer engineers have designed it with DriveTronic shaftless drives that allow the demands of high-precision multicolor flexo post-printing “to be easily achieved.” It allows operators to set up while production is running, and facilitates fast job changes and low-maintenance. It also provides operators with integrated error diagnostics and online remote maintenance. Users control the machine with a flexible Profibus system and easy-to-use ergonomic touchscreen. Its production management system permits the saving of repeat jobs and the automatic presetting of job parameters. Integrated error diagnostics and online remote maintenance also “surpass general standards.”
Sheets are carried in exact register from the feeder, via the printing units to the rotary die-cutter by way of a continuous overhead vacuum transport system. The direc- drive technology also allows the use of different printing plate thicknesses by compensating the circumferential speed of the cylinder. The CorruCUT printing units are fitted with a proven, quick-clamp chamber blade system made from carbon fibre composite. The low volume of the chamber blade results in optimum ink transfer and minimal ink loss during washing. The ink supply and the automatic washing system are designed to achieve the best possible results with low water consumption and fast washing times.
